Answer:
Radiocarbon measurement or radiocarbon dating is a method that is used to measure the age of the carbon-based material in living organisms.
Radiocarbon dating is able to estimate age of fossils that are younger than 50,000 years and unable to measure things that died longer than 200,000 years ago because fossils that are too old do not contain carbon or carbon get vanished from too old fossils of organisms. Some of the fossils also get contaminated due to environmental conditions and during teh collection or preservation process.
Thus, radiocarbon measurement is useless when trying to measure most rocks older than 50,000 years.

Hi There! I'm new so I hope I get This Right! ^^
Explanation:
double blind test. the control group receives a placebo. Why is a placebo used in a double-blind test? so that the effects on people in two different groups can be compared.
happy To Help! ^^
Given what we know, the most appropriate way to find the concentration of orange candies is to take the exact number of orange candies and divide it by the total number of candies present.
<h3>Why is this the best method?</h3>
- This is the best method because it allows us to obtain a decimal value.
- This value will represent the percentage of candies in the total that are orange.
- In order to pass this decimal into a percent value, all we have to do is multiply by 100.
Therefore, we can conclude that by taking the total amount of orange candies and dividing by the total number of candies, we can obtain a decimal to illustrate the percent of total candies that are orange.

Answer:
365.4 g/mol is the molar mass of this gas.
Explanation:
Using ideal gas equation:
PV = nRT
where,
P = Pressure of gas = 0.98 atm
V = Volume of gas = 1.5 L
n = number of moles of gas = ?
R = Gas constant = 0.0821 L.atm/mol.K
T = Temperature of gas = 287 K
Putting values in above equation, we get:
Moles of gas = n = 0.06239 mol
Mass of gas = m = 22.8 g
Molar mass of gas = M
365.4 g/mol is the molar mass of this gas.
Hello!
False.
The equation to calculate force, according to Newton's Second Law, is equivalent to F = m · a where:
m = mass of the object
a = acceleration of the object
Those two multiplied are equivalent to force.
